Help to the undeserving leads to misfortune (Pride and Prejudice)

When Darcy’s father died and Wickham rejected the living offered to him at the vicarage, Darcy agreed to give him a princely sum of ₤3000 settlement instead. As childhood companions, he did this after he fully knew Wickham’s character. In return for that generosity, Wickham tried to elope with Georgiana and gain her fortune by deceit. That is the gratitude of an undeserving man to his benefactor. Later Darcy has to pay off Wickham to marry Lydia. Giving more than the occasion or the person deserves leads to misfortune.
